LEFT LED s Power (Ethernet) Description of Operation Green Indicates Power is being supplied to the DL6000. Flashes GREE for 0.5 seconds when a character is Received or Transmitted. If Characters are being received of transmitted faster than this then it might appear the LED is on SOLID. Flashes RED for 0.5 seconds if a AK is received or transmitted. Will also flash if all serial communication buffers are full. A-B etwork (DH+ ) On Hardware Reset will flash GREE and RED until a valid DH+ network is detected. This is the AUTO BAUD Rate detection mode, the DL6000 will automatically connect at the DH+ speeds of 57.6K, 115.2K and 230.4K Baud. LED will switch to on solid once the DL6000 is on the DH+ network as a valid node address. LED will flash GREE when the DH+ is set to a certain Baud rate but is not on network. (DH-485) On Hardware reset the A-B etwork will flash GREE at a 1 second rate when the DH-485 is not on network. Once a valid network is running the LED will flash GREE much more rapidly (approx. every 0.1 seconds), the rate depends on how busy the network is. Status Used for Determining Operating Mode and DL6000 Status RJ45 LED s Description of Operation Activity LED Link LED Blinks (amber 10BaseT) or (green 100BaseT) to indicate an Ethernet socket has been established and active.

29 5.4 Allan-Bradley etwork Configuration The DH+ or DH-485 requires that every station on the network has its own node address. This section describes the configuration of the DL6000 for the desired A-B network DH+ ode Address The DH+ network allows up to 64 nodes on a network with addresses ranging from 0 to 63 decimal. The DL6000 DH+ node address is determined from the last octet of the IP address assigned to the unit. The following table shows how the DH+ node address is determined from the last octet of the IP address. ode Address Last Octet of IP address If the last octet of the IP address is larger than 63, subtract 64 from the value until it falls within the range of 0 to 63. This will be the DH+ node address in decimal. Since DH+ uses octal notation, a conversion decimal to octal will be needed. Ex. DL6000 with IP Address Solution Take the last octet and subtract and keep subtracting 64 until the value falls within the range of 0 to The DH+ node address is 42 decimal or 52 octal DH+ Baud Rate The DH+ Baud rate on the DL6000 is auto detecting; whatever the existing network is set to the DL6000 will use that baud rate. Valid rates of 57.6K, 115.2K and 230.4K Baud are supported. On Hardware Reset the A-B etwork (CHA) LED will flash GREE and RED until a valid DH+ network is detected. This is the AUTO BAUD Rate detection Mode and the DL6000 will stay in this mode until a valid network is connected to the A-B etwork Connector. The A-B etwork LED will then switch to on solid once the DL6000 is on the DH+ network as a valid node address. 29

30 5.4.3 DH-485 ode Address The DH-485 network allows up to 32 nodes on a network with addresses ranging from 0 to 31 decimal. The DL6000 DH-485 node address is determined from the last octet of the IP address assigned to the unit. The following table shows how the DH-485 node address is determined from the last octet of the IP address. ode Address Last Octet of IP address If the last octet of the IP address is larger than 31, subtract 32 from the value until it falls within the range of 0 to 31. This will be the DH-485 node address in decimal. Ex. DL6000 with IP Address Solution Take the last octet and subtract and keep subtracting 32 until the value falls within the range of 0 to The DH-485 node address is 10 decimal DH-485 Baud Rate The DH-485 Baud rate will set itself to 19.2K if the Serial Interface was set to or Higher. Otherwise it will use 9600 for a 9600 baud and 4800 for 4800 baud. Serial Interface Speed DH-485 Speed Baud 19.2K Baud 9600 Baud 9600 Buad 4800 Baud 4800 Buad 30

36 8 DL6000 Typical Applications The DL6000 is designed to be used in applications using Ethernet to communicate with devices on a DH+ or DH-485 network. Some of the typical applications that use the DL6000 are shown in this section. 8.1 DL6000-MEDH+ The following example shows a SCADA server using a DL6000 to acquire data from PLC s and devices on the DH+ network. 36

37 9 Frequently Encountered Problems This section outlines some of the most frequently encountered problems when trying to configure the DL6000. If the problem you are having is not located in this section, please contact technical support. 9.1 Device Installer cannot find the DL6000 If for some reason the Device Installer software cannot find the DL6000 on the Ethernet network, it can possibly be because one of the following problems: 1. Another device on the Ethernet network has the same IP address that is currently assigned to the DL The DL6000 may have an IP address in which the network ID portion of the address does not match the network ID that is being used by the Ethernet network. In order to assign an IP address to the DL6000, the address resolution protocol (ARP) will be used. Using the ARP command will only temporarily change the IP address in the device. To configure the unit so that it keeps the IP address, you must telnet to the unit and change its IP address from the configuration menu. In order for the ARP command to work in Windows 95, the ARP table on the PC must have at least one IP address defined other than its own. To use the ARP command to assign a temporary IP address, follow the steps below. 1. Open an MS DOS command prompt window. 2. At the command prompt, type the following to view the ARP table. arp a To add another value to the ARP table, ping another device on the current network. 3. Use the following ARP command to add the DL6000 to the ARP table. arp s xxx.xxx.xxx.xxx aa-bb-cc-dd-ee-ff The first entry after the arp s is the IP address that you wish to temporarily assign to the DL6000 (denoted by xxx.xxx.xxx.xxx). The next entry is the MAC address of the DL6000 which can be located on the bottom of the unit (denoted by aa-bb-cc-dd-eeff). 4. Open a telnet session to the DL6000 using port 1. This is done by typing the following at the command prompt. telnet xxx.xxx.xxx.xxx 1 37

38 The connection will fail when this is done, but will temporarily change the IP address of the DL6000 to xxx.xxx.xxx.xxx. 5. Finally open another telnet session but this time to port 9999 as follows. telnet xxx.xxx.xxx.xxx Set the IP address of the DL6000 by changing the etwork or Server settings from the main menu of the telnet session. The IP address assigned here will become the permanent IP address of the DL Cannot communicate to DH+ node 0 using the DL6000-MEDH+ Any Modbus client that is trying to read or write data to a PLC or device on the DH+ or DH-485 at node 0 will not work. The reason for this is because the Modbus protocol uses slave ID 0 as the broadcast address. All Modbus slaves recognize the broadcast address but do not send a response when a broadcast message has been received. 38

39 Appendix A: TCP/IP Tutorial This section is design to guide you to gain a brief understanding to TCP/IP addressing mechanism and the meaning behind the DL6000 IP configurations. TCP/IP suite is the most commonly used Ethernet communication protocol in both industrial and commercial networking applications. The protocol implements a two-level addressing mechanism in order to assign a computer or other Ethernet device (1) its ode Address (Host ID), and (2) its etwork Address (etwork ID). With the node address, the Ethernet device can identify itself on a network; with the network address, the Ethernet device can identify the network in which it belongs to, and facilitate communication among computers across different networks. Analogy The node address is analogous to the suite number in an apartment, and the network address is equivalent to the residential number of the entire apartment building. When my friends want to visit me, I must give them both my suite number and the residential number of the apartment in which I live in, else they wouldn t be able to find my place. A.1 IP Address TCP/IP uses a four-segmented number set to store the node address and the network address; the number in every segment varies from 0 to 255, and segments are separated by decimal points. This segmented number set is called the IP Address, and has the appearance of XXX.XXX.XXX.XXX. Ex. Here are some valid IP addresses: (reserved for Local Area etwork applications) ( ( (etworking Interface Card Loopback IP) 39

40 A.2 Subnet Mask At this point, one may start to wonder how to identify the node address and the network address from the four number segments. Sadly, with only the IP address, no one can meaningfully separate the node address from the network address, not even computers. What is needed in addition to IP address is the Address Delimiter The Subnet Mask. A Subnet Mask has the same format as the IP address (XXX.XXX.XXX.XXX); however, the segments are usually filled with either 255 or 0. Ex. Here are some valid subnet masks: (Class C Subnet Mask) (Class B Subnet Mask) A.3 IP Address and Subnet Mask Couple When combining IP address with Subnet Masks, the node address can be separated from the network address in this way: (1) the node address is the IP address segment that maps to the Subnet Mask segment(s) that is/are filled with 0; (2) the network address is the IP address segment that maps to the Subnet Mask segment(s) that is/are filled with 255. Ex. Illustration of IP address / Subnet Mask mapping rule: IP address Subnet Mask Solution This IP address couple gives you: ode Address 3 etwork Address ote: The IP address/subnet Mask mapping rule introduced above is generally true for most of the TCP/IP networking applications; in some specialized networks, network administrators can enter numbers other than 255 or 0 in the Subnet Mask segments for network customizations. However, this advance TCP/IP application is beyond the scope of this tutorial. 40

41 A.4 Valid IP Addresses Although the IP address / Subnet Masks couple gives a phenomenally large number of possible combinations of node/network address, only certain combinations are valid. Here are some general classifications of valid IP addresses: Local Area etwork x.x This set of IP addresses is reserved for addressing in Local Area etwork (the network that is not connected directly to the internet, but through routers or gateways) This IP address points to the ode itself. (Loopback Address) This IP points to current network. ode Address of 255 This IP address points to every nodes on the network. (Broadcast Address) ode Address of 0 This IP address points to the entire network with the network address described in the IP address. Wide Area etwork / Internet When connected to the internet, network nodes must use the IP Addresses from the following Categories: Class A IP Address IP addresses with the first segment ranging from 1 to 127, and subnet mask Class B IP Address IP addresses with the first segment ranging from 128 to 191, and subnet mask Class C IP Address IP addresses with the first segment ranging from 192 to 223, and subnet mask

42 Class D IP Address (Multicast) IP addresses with the first segment ranging from 224 to 239. Class E IP Addresses (Reserved) IP addresses from 240 and above in the first segment. ote: 1. These IP address regulations are weakly enforced; users are allowed to violate these rules. In Local Area etwork applications, IP rule violation will not cause problems on network connectivity. However, when connected to the internet, users are expected to strictly conform to the IP regulations to ensure valid connectivity. For more in-depth information on IP address regulation, please consult your networking administrator. 2. Since 1993, the Classful IP address regulation has no longer been the only IP rules implemented on the internet. Many inter service providers (ISPs) adopted class-less IP address regulations, in which the IP address / Subnet Mask couple is interpreted differently than in classful IP address. Detail information on class-less IP address regulations is out of the scope of this tutorial. 42
